CAUTION: To ensure proper system cooling, memory module blanks must be installed in any memory socket that
is not occupied. Remove memory module blanks only if you intend to install memory modules in those sockets.
Steps
1. Locate the appropriate memory module socket.
2. Push the ejectors outward on both ends of the memory module socket, to release the memory module from the socket.
3. Lift and remove the memory module from the system.
Installing memory modules
Steps
1. Locate the appropriate memory module socket.
2. Open the ejectors on the memory module socket outward to allow the memory module to be inserted into the socket.
3. Align the edge connector of the memory module with the alignment key of the memory module socket, and insert the
memory module in the socket.
CAUTION: Do not apply pressure at the center of the memory module; apply pressure at both ends of the
memory module evenly.
NOTE: The memory module socket has an alignment key that enables you to install the memory module in the socket in
only one orientation.
4. Press the memory module with your thumbs until the socket levers firmly click into place.
5. Repeat step 1 through step 4 of this procedure to install the remaining memory modules.
Next steps
1. If applicable, install the air shroud.
2. To verify if the memory module has been installed properly, press F2 and navigate to System Setup Main Menu> System
BIOS > Memory Settings. In the Memory Settings screen, the System Memory Size must reflect the updated capacity of
the installed memory.
3. If the value is incorrect, one or more of the memory modules may not be installed properly. Ensure that the memory module
is firmly seated in the memory module socket.
4. Run the system memory test in system diagnostics.
